For a spacecraft launched half a century ago, it's unbelievable that it still works at all.

On the one hand, it has crashed into a lot of somethings—like cosmic radiation and micrometeorites. On the other hand, there is a lot of space in space, and the chances of Voyager crashing into something of the same or larger scale as itself is infinitesimal.

Whatever happened, it was temporary, because radio contact was established again after a 2-day pause.

If it did crash into anything probably like a grain or sand or something stupid like that.
